It might suggest that the downloaded files has become corrupted.

Try and check your harddrive for errors and try downloading the update again, preferably through a cabled connection instead of wireless.

Check Hard Drive For Errors And Corrupted Files

All files can become damaged. This is just the nature of hard drives. If this affects the Punkbuster files this can cause errors and it's therefore a good idea to scan your hard drive. Do this for all hard drives that has Windows, Punkbuster and the game installed.

1. Go to "This PC" in Windows and right click the hard drive and click "properties"
   
2. Go to "Tools" and and press "Check"
   
3. Click "Scan Drive" and let it scan for errors.
4. If it finds errors let the program fix them
   (If there are errors it could mean nothing, but it can also suggest that it might be time to format your computer and/or replace the hard drive)
5. Reboot your computer
6. Run the scan again
7. Keep repeating step 3-5 until no errors are found.
